 All relevant changes are documented in this file.
 
+[4.11][] - 2025-03-27
+---------------------
+
+### Changes
+ - Update documentation regarding transition from runlevel S to 2, how
+   run/tasks must "complete" before Finit can move to the next runlevel
+ - Improve argument handling in bundled getty when launching login
+
+### Fixes
+ - Fix #432: allow services in `setup` state to be stopped.  This fixes
+   a serious blocker introduced in 4.10 that prevented systems from
+   being rebooted when any service was in this state
+ - Fix fallback `SIGKILL` when stopping a service with `SIGTERM` does
+   not work.  This fixes a serious issue with services not responding to
+   the default `SIGTERM`
+ - Fix pre/post/ready/cleanup script execution if service has an
+   optional `env:file` (leading `-`)
+
+
+[4.10][] - 2025-03-03
+---------------------
+
+### Changes
+ - Add support for `cleanup:[0-3600,]script`, runs before service is
+   removed, unlike `post:script` that runs when service is stopped
+ - Improved entropy gathering in tertiary fallback of urandom plugin
+ - Reclassify `sysv` from run/task class to `service`
+
+### Fixes
+ - Fix #427: using an external getty with custom login program cause
+   Finit to use login program as the getty command
+ - Fix #428: allow `sysctl` path to be set at build time
+ - Fix #429: regression in v4.9 causing Finit to segfault at shutdown
+ - Fix possible memory leak when sourcing a service `env:file`
+ - Finit now waits until all `post:scripts` have run before returning
+   OK to `initctl <reload|runlevel>`.  This also applies to the new
+   `cleanup:scripts` introduced in this release
+ - RFC3154 conformance formatting fix for `/dev/kmsg` fallback logging
+
+
+[4.9][] - 2025-02-15

+> This release changes how Finit reacts to the exit status of `pre:`
+> scripts.  Finit will now no longer start the main process if its
+> `pre:` script fails for any reason.  So, if you have pre scripts that,
+> e.g., create directories, make sure they are idempotent.
+
+### Changes
+ - Add individual timeout (optional) support for pre/post/ready scripts
+ - Add support for systems with broken RTC, i.e., those that at power-on
+   may reset the RTC to a random date instead of zero, issue #418
+ - Add support for detecting "in-container" when in `systemd-nspawn`
+ - Check exit status of `pre:` scripts, on failure drive service/sysv to
+   `crashed` state.  (The exit code of `post:` scripts remain ignored)
+ - All pre/post/ready scripts are now also searched for in `$PATH`
+ - Reset color attributes and clear screen when starting up.  This is
+   for boot loaders like GRUB, which leave background color artifacts
+
+### Fixes
+ - Fix #415: only mark reverse-dependencies "dirty" if the main service
+   does not support SIGHUP.  This helps avoid unnecessary restarts of
+   services that depend on a service that supports SIGHUP
+ - Fix #417: leaking inotify watchers in the cgroup subsystem
+ - Fix #421: add support for `nofail` mount option in `/etc/fstab`
+ - Fix #425: ordering bug in detecting .conf file changes to services
+   and `initctl reload`, or runlevel changes
+ - Fix `initctl touch` of template services, previously marking a
+   service created from a template as "dirty" did not take
+ - Fix unintended restart of template "siblings".  I.e., `initctl touch`
+   of instantiated template service A affected B from same template
+ - Fix buggy `--with-rtc-date=DATE` configure option
+ - Fix kill on timeout of pre/post/ready scripts
+
+

+--------------------
+
+### Changes
+ - Avoid remounting already mounted `/run` and `/tmp` directories.  This
+   extends the existing support for detecting mounted directories to
+   include complex mount hierarchies are in use, overlayfs and tmpfs
+   mounts.  Feature by Mathias Thore, Atlas Copco
+ - getty: trigger /etc/issue compat mode for Alpine Linux
+ - tmpfiles.d: skip `x11.conf` unless X11 common plugin is enabled
+ - tmpfiles.d: ignore x/X command, nos support for cleanup at runtime
+ - Drop debug mode `-D` from `udevd` in `hotplug.conf.in`, allow the
+   user to set this in `/etc/default/udevd` instead
+ - Certain initctl APIs at bootstrap are not supported, update warning
+   log to include command (number) for troubleshooting, issue #398
+ - Add support for hwrng to urandom plugin and check for empty seed
+ - Add `runparts -b` (batch mode) support, disables escape sequences
+ - New configure `--without-rc-local`, disables `/etc/rc.local` support
+ - New configure `--disable-cgroup` option, disables cgroup v2 detection
+ - `initctl show template@foo.conf` now shows how an enabled template
+   service has been evaluated by Finit, issue #411
+ - Extend `initctl` timeout connecting and waiting for Finit reply.  The
+   previous 2 + 2 second poll timeout has proved to be too short on more
+   complex systems.  Now a 15 + 15 second timeout is applied which should
+   be more resistant to temporary overload scenarios, issue #407
+
+### Fixes
+ - Fix #397: system shutdown/reboot can block on console input if action
+   is started remotely (ssh).  Caused by legacy TTY screen size probing,
+   removed from both bootstrap and shutdown/reboot
+ - Fix #400: both `HOOK_MOUNT_ERROR` and `sulogin()` fail to trigger on
+   either mount or `fsck` errors.  Problem caused by unresolved status
+   from pipe, calling `pclose()` without extracting exit status
+ - Fix #402: `initctl touch` does not respect `-n` (no error) flag
+ - Fix #403: `initctl touch` does not support template services
+ - Fix #404: possible undefined behavior when `--with-fstab=no` is set
+ - Fix #405: `@console` getty does not work with `tty0 ttyS0`
+ - Fix #409: prevent tmpfiles from following symlinks for `L+` and `R`,
+   otherwise symlink targets would also be removed.  Found and fixed by
+   Mathias Thore and Ming Liu, Atlas Copco
+ - Fix #414: Frr Zebra immediately restarts on `initctl stop zebra`.
+   The fix likely works for all Frr/Quagga services due to the way they
+   create and delete their pid file
+ - Cosmetic issue with `[ OK ]` messages being printed out of order at
+   shutdown/reboot.  Caused by nested calls to `service_stop()`
+ - Cosmetic issue with duplicate "Restoring RTC" message at bootstrap
+

+
+### Fixes
+- Fix #383: dbus and runparts regression in Finit v4.5.  The configure
+  script must expand `FINIT_RUNPATH_` before defining it in `config.h`
+- Fix #384: service environment variables drop everything but the first

+
+
+[4.5][] - 2023-10-30
+--------------------
+
+### Changes
+- Refactor `runparts` and `/etc/rc.local` to no longer block the main
+  loop, allowing `initctl` calls to interact with Finit.  Issue #356
+- Refactor the `run` stanza to no longer block the main loop, issue #362
+- Allow `sulogin` with a user different from `root`, issue #357
+- Allow disabling invocation of rescue mode from kernel command line
+- Add `initctl -f` to force-skip asking Finit for existing services
+  when creating new services during bootstrap, e.g. `/etc/rc.local`
+- `initctl runlevel` now returns `N S` instead of `N 10` in bootstrap
+- `initctl runlevel N` during bootstrap is now allowed.  It changes
+  the next runlevel to go to when bootstrap has completed.  Effectively
+  overriding the `runlevel N` statement in `/etc/finit.conf`
+- Improved logging on failure to `execvp()` a run/task/service, now
+  with `errno`, e.g., "No such file or directory" when the command
+  is missing from `$PATH`
+- Add Bash completion support for `initctl`, configurable, issue #360
+- Handle absolute path to `initctl [enable|disable]`, not supported
+- Update `finit.conf(5)` man page with the recommended directory
+  hierarchy in `/etc/finit.d/`
+- The `runparts` code has been split into `/libexec/finit/runparts`
+- The `runparts` command now takes two options: `sysv` and `progress`.
+  The former ensures only `SNNfoo` and `KNNfoo` scripts are run.
+- Add SysV Init Compatibility section to documentation
+- Increased MAX path for commands, and arguments: 64 -> 256
+- The bundled watchdog daemon no longer tries to log at startup, because
+  syslog is not available yet, any startup message leak to console
+- Extend `if:` option with runtime evaluation of conditions.  E.g., start
+  a task only `if:<run/foo/failure>` (here the run task 'foo' failed)
+- Document new `if:`, `conflict:`, `nowarn` options for run/task/service
+  first introduced in v4.4
+- Failure to open fstab should log to console, not just log to `/dev/kmsg`
+- Rename `/lib/finit/system/*.conf`, added numbered prefix to ensure
+  proper execution order, e.g., `udevd` should always run first
+- Plugins and bundled services: dbus, keventd, watchdogd, and runparts,
+  are now loaded *after* all services in `/lib/finit/system/`.  A new
+  runtime-only path (for inspection) in `/run/finit/system/` is used
+- Redirect `log*` output to console when `finit.debug` is enabled
+- Assert `<int/container>` condition if we detect running in container
+- Add support for mdev's netlink daemon mode, issue #367
+- Add support for mdevd in `10-hotplug.conf`, preferred over plain mdev
+- Disable modprobe plugin by default, udevd and mdev/mdevd loads modules
+- Update documentation for run/task shell limitations, issue #376
+- Update documentation regarding automount of `/run` and `/tmp`
+- Update plugin documentation, add section about limited tmpfiles.d(5) support
+- Skip registering service when `if:!name` matches a known service.
+  This allows conditional loading of alternative services, e.g. if udevd
+  is already loaded we do not need mdevd
+- Drop `doc/bootstrap.md`, inaccurate and confusing to users
+
+### Fixes
+- Fix #227: believed to have been fixed in v4.3, the root cause was
+  actually that Finit was waiting for a process that was no longer in
+  the system.  The fix is to ask the kernel on process-stop-timeout and
+  replay the lost PID so that Finit can continue with reboot/shutdown
+- Fix #358: fix inotify events for `/etc/finit.conf`, improved log
+  messages and error handling
+- Fix #361: cgroup move fail if run/task/services start as non-root.
+  Regression in the v4.4 release cycle while adding support for the
+  pre:/post:/ready: scripts.  Now the latter scripts also properly run
+  in their correct cgroup
+- Fix #366: document `fsck.*` kernel command line options and simplify
+  the configure flags `--enable-fsckfix` and `--enable-fastboot` to
+  only adjust the default values for the `fsck.*` options.
+- Fix #371: swap load order of `/lib/finit/system/*` vs `/etc/finit.d/*`
+  We must run `10-hotplug.conf` first to ensure devices and modules are
+  up and loaded before the user's run/task/services are called.  The order
+  at bootstrap is now saved in `/run/finit/conf.order` for inspection,
+  `/run/finit/exec.order` shows the start order of each process
+- Fix #372: lost `udevadm` calls due to overloading
+- Adjust final `udevadm settle` timeout: 5 -> 30 sec
+- Fixed dbus plugin, the function that located `<pidfile> ...` in the
+  `dbus/system.conf` caused spurious line breaks which led to the
+  service not being loaded properly
+- The `runparts` executor now skips backup files (`foo~`)
+- The `runparts` stanza now properly appends ` start` to scripts that
+  start with `S[0-9]+`.  This has been broken for a very long time.
+- Fix #377: expand service `env:file` variables, allow constructs like:
+
+        RUNDIR=/var/run/somesvc
+        DAEMON_ARGS=--workdir $RUNDIR --other-args...
+- Fix #378: warn on console if run/task times out during bootstrap
+- Fix #378: add run/task support for `<!>` to allow transition from
+  bootstrap to multi-user runlevel even though task has not run yet.
+- Fix #382: do not clear `<service/foo/STATE>` conditions on reload.  
+  Introduced back in v4.3-rc2, 82cc10be8, the support for automatic
+  service conditions have had a weird and unintended behavior.  Any
+  change in state (see `doc/svc-machine.png`) caused Finit to clear
+  out *all* previously acquired service conditions.
+
+  However, when moving between RUNNING and PAUSED states, a service
+  should not have its conditions cleared.  The PAUSED state, seen
+  also by all conditions moving to FLUX, is only temporary while an
+  `initctl reload` is processed.  If a service has no changes to be
+  applied it will move back to RUNNING.
+
+  Also, we cannot clear the service conditions because other run/task
+  or services may depend on it and clearing them would cause Finit to
+  `SIGTERM` these processes (since they are no longer eligible to run).
+

+
+> **Note 1:** this release contains changes to the `.conf` parser.  If you

+> for, e.g., `sysklogd`.  Issue #352
+
+### Changes
+* Add limited tmpfiles.d(5) support
+
+  This change adds very basic `tmpfiles.d/` support to Finit.  Most of
+  the basic types are supported, but not all, so for now, please check
+  the code and examples for details on what is working.
+
+* If a run/task/service command does not exist, skip registering it
+
+  This changes the semantics of Finit a bit by checking for the command
+  to run when registering it, skipping commands that cannot be found in
+  the absolute path provided in the command, or in `$PATH`
+
+  This change includes a new `nowarn` flag that can be used to prevent
+  Finit from warning for missing commands.  See below for an example.
+
+* Add run/task/service support for `conflict:foo` handling
+* Add run/task/service support for `if:[!]ident` and `if:<[!]cond>`
+
+  Conditional loading of stanza depending on ident is already loaded (or
+  not), or condition satisfied (or not).  E.g., do not run `mdev` if we
+  found and registered `udevd`, or load service only if `<boot/testing>`
+  condition is set.
+
+  The optional leading `!` negates the comparison, if NOT foo then ...
+
+* Add support for static services in `/lib/finit/system/*.conf`
+
+  Slowly migrating away from hard-coded services in plugins.  This way
+  it's possible for the user to both inspect and override as needed.
+
+* Migrate hotplug plugin to a conditional `/lib/finit/system/hotplug.conf`
+
+  This is the first example of the just minted advanced stanza syntax with
+  `if:`-statements, `conflict:` handling, and `nowarn` flags.
+
+* Initial support for template services, `foo@.conf`, similar to systemd
+
+        $ initctl show avahi-autoipd@
+        service :%i avahi-autoipd --syslog %i -- ZeroConf for %i
+
+  To enable ZeroConf for, e.g., `eth0`, use
+
+        $ initctl enable avahi-autoipd@eth0.conf
+
+  The enabled symlink will be set up to `avahi-autoipd@.conf` and every
+  instance of `%i` will in the instantiated directive be replaced with
+  `eth0`.  Inspect the result with:
+
+        $ initctl status avahi-autoipd:eth0
+
+* Add `devmon`, a `<dev/foo>` condition provider, issue #185
+* Support for line continuation character `\` in .conf files, issue #186
+
+        service name:sysklogd [S123456789]   \
+            env:-/etc/default/sysklogd       \
+            syslogd -F $SYSLOGD_ARGS         \
+            -- System log daemon
+
+* `HOOK_BASEFS_UP` has been moved!  External plugins that need to call
+  `service_register()`, please use `HOOK_SVC_PLUGIN` from now on.  
+  Apologies for any inconveniences this might cause!
+* getty: add support for `/etc/os-release` to replace `uname` output  
+  This change, which has a fallback to `/usr/lib/os-release`, overrides
+  traditional modifiers with the os-release variant.  These values were
+  taken from `uname`, which on Linux systems are pretty useless since
+  they always return the kernel name and version instead of the
+  distro/OS values.
+
+  E.g., \s becomes `PRETTY_NAME` instead of 'Linux' and \v becomes the
+  pretty `VERSION`, while \r becomes `VERSION_ID`.
+* Support for overriding `/etc/finit.conf` and `/etc/finit.d` issue #235  
+  New (kernel) command line option `finit.config=PATH` which can be used
+  to redirect Finit to start up with, e.g., `/etc/factory.conf` instead of
+  `/etc/finit.conf`.
+
+  For the complete experience a new top-level configuration file directive
+  `rcsd PATH` has also been added.  It in turn can be used by `factory.conf`
+  as follows to override `/etc/finit.d`:
+
+        rcsd /etc/factory.d
+
+* Support for overriding `/etc/finit.d` from the alternate `finit.conf`
+  with a new `rcsd /path/to/dot.d/` .conf file directive
+* Support for `fsck_mode=[auto,skip,force]` + `fsck_repair=[preen,no,yes]`
+* Add `set` keyword for environment variables set in `/etc/finit.conf`
+* Support `finit.cond=foo` cmdline `<boot/foo>` conditions, issue #250
+* `initctl` JSON output support for status and conditions, issue #273  
+  Example:
+
+        root@infix:~$ initctl status -j resolvconf
+        {
+          "identity": "resolvconf",
+          "description": "Update DNS configuration",
+          "type": "task",
+          "forking": false,
+          "status": "done",
+          "exit": { "code": 0 },
+          "origin": "/etc/finit.d/enabled/sysrepo.conf",
+          "command": "resolvconf -u",
+          "restarts": 0,
+          "pidfile": "none",
+          "pid": 0,
+          "user": "root",
+          "group": "root",
+          "uptime": 0,
+          "runlevels": [ 1, 2, 3, 4, 5, 7, 8, 9 ]
+        }
+
+  The excellent tool `jq` can be used to extract parts of the output for
+  further scripting.  E.g. `initctl status -j foo | jq .exit.status`
+
+* Add JSON support to `initctl ls` command  
+
+  This allows for easy access to the *disabled* services:
+
+        root@anarchy:~# initctl ls --json |jq '.available - .enabled'
+        [
+          "chronyd.conf",
+          "dnsmasq.conf",
+          "gdbserver.conf",
+          "inadyn.conf",
+          "inetd.conf",
+          "isisd.conf",
+          "lldpd.conf",
+          "mstpd.conf",
+          "ntpd.conf",
+          "ospf6d.conf",
+          "ospfd.conf",
+          "querierd.conf",
+          "ripd.conf",
+          "ripng.conf",
+          "sshd.conf",
+          "syslogd.conf",
+          "telnetd.conf",
+          "uftpd.conf",
+          "wpa_supplicant.conf",
+          "zebra.conf"
+        ]
+
+* Allow `manual:yes` on sysv/service/run/task stanzas, issue #274
+* Add support for `oncrash:script` to call the `post:script` action, if
+  defined, for a crashing service.  The `EXIT_CODE` variable sent to the
+  script is set to `crashed`. Issue #282
+* Search for plugins in `/usr` and `/usr/local` as well, issue #284
+* tty: add support for `passenv` flag to `/bin/login`, issue #286
+* Add reboot/shutdown/poweroff timeout `-t SEC` to initctl, issue #295
+* Add support for s6 and systemd readiness notification, issue #299.  
+  Service readiness notification to support daemons employing systemd
+  and s6 notification.  Complementing the native Finit readiness support
+  using PID files that exist already.
+
+  The two have slightly different ways of implementing readiness:
+
+  - https://www.freedesktop.org/software/systemd/man/sd_notify.html
+  - https://skarnet.org/software/s6/notifywhenup.html
+
+  Finit now provides both a `NOTIFY_SOCKET` environment variable, for
+  systemd, and a way to start s6 daemons with a descriptor argument.
+
+  For details on the syntax, see the `service` documentation.
+
+  This change also renames internal states for run/task/services to
+  avoid any confusion with the introduction of `ready:scripts`:
+
+  - `WAITING -> PAUSED`
+  - `READY   -> WAITING`
+
+  A service condition that used, e.g., `<service/foo/ready>` should now
+  instead use `<service/foo/waiting>`
+
+* Add `ready:script` for services, called when daemon is ready, issue #300
+* Add support for running scripts at shutdown at two new hook points
+  during the shutdown process, issue #302. See doc/plugins.md for details:
+
+  - `HOOK_SVC_DN`: after all services and non-reserved processes have been
+    killed (and collected)
+  - `HOOK_SYS_DN`: after all file systems have been unmounted, *just prior*
+    to Finit calling `reboot()` to shut down or reboot the system
+
+* The `modules-load` plugin now default to runlevel `[S]`, in previous
+  releases it was `[2345]`.  This breaking change is to align it more
+  with what users mostly want (modules loaded before services start) and
+  can be changed back to the old behavior with a per-file setting:
+
+        set runlevel 2345
+
+* The `modules-load` plugin now adds silent tasks for modprobe.  This to
+  prevent confusing `[ OK ]` boot messages when in fact modprobe failed.
+* The `modules-load` plugin now support `set modprobe /path/to/modprobe`
+* The header files `finit/conf.h` and `finit/service.h` are now exported
+  for external plugins
+* Add support for multiple args to `initctl cond set/clr`, issue #329
+* Silence confusing `[ OK ]` progress from modules-load plugin, issue #332  
+
+  This change drops the confusing status progress output, which was always
+  OK since the actual modprobe operation runs in the background.  No need
+  to show status of the "added a task to finit, found modprobe" command.
+
+* dbus plugin: adapt to other operating systems
+
+  Not all Linux systems are based on Debian, and even if they are inspired
+  by Debian (Buildroot), they do not necessarily use the same defaults.
+  Probes the system at runtime for:
+
+  - dbus user and group
+  - dbus PID file
+
+  If the user/group cannot be found we fall back to `root`, if the PID
+  file cannot be determined we ignore PID file readiness.
+
+* Improve documentation for runparts and hook scripts.  Issue #315, #320
+* Add `HOOK_NETWORK_DN`, called after change to runlevel 6 or 0, issue #319
+* Use sysklogd `logger` tool instead of legacy `logit` tool, issue #344
+
+  For log redirection Finit has the legacy `logit` tool.  This change
+  allows Finit to use the `sysklogd` project's extended `logger` tool
+  instead, when available.  Allowing logging with the process' PID.
+
+* Add `initctl` aliases: `cat -> show`, `kill -> signal`
+* Add `initctl -n,--noerr` to return OK(0) if services do not exist, for
+  integration with openresolv and scripts with similar requirements
+* Add `initctl plugins`, list installed plugins
+* Add timestamp to log messages in fallback and logging to `stderr`.  
+  When there is no log daemon, and we are running in a container, or we
+  cannot log to the kernel ring buffer, then we log to `stderr`.  This
+  change improves log output by prefixing each message with a timestamp.
+
+### Fixes
+* Fix #254: document limitations in `rc.local` and `runparts` scripts
+* Fix #269: add compulsory kernel symlinks in `/dev`
+* Fix #275: `initctl status foo` should list all instances, regression
+  introduced in v4.3
+* Fix #278: enforce conditions also for running `pre:` scripts
+* Fix #279: allow `restart:always`, of crashing services.  Similar to
+  `respawn` but honors `restart_sec`
+* Fix #280: allow calling `initctl restart foo` from within foo
+* Fix #283: too quick timeout at bootstrap of lingering tasks
+* Fix #285: `initctl restart` should start crashed service
+* Fix #288: enable built-in `sulogin` in Alpine and Void Linux builds
+* Fix #293: modprobe plugin: support for coldplugging more devices.  It
+  turns out, not all buses in Linux add `modalias` attributes to their
+  devices in sysfs.  One notable exception are MDIO buses.  The plugin's
+  scan routine would thus not pick them up.
+* Fix #294: `shutdown --help` mistakenly shuts down system
+* Fix #310: Always use configured restart delay for crashing services.
+  If no delay is configured, default to an initial 2000 msec for forking
+  daemons and start-stop scripts, and 1 msec for non-forking daemons
+* Fix #311: document how to combine device tree with conditions
+* Fix #312: restart services with respawn set, e.g. ttys, immediately
+* Fix #313: Cancel pending restart timer on stop/start/restart/reload
+* Fix #314: skip run/task/service restart if conditions are lost
+* Fix #315: add environment variables to hook scripts
+
+  All hook scripts are called with at least one environment variable
+  set, `FINIT_HOOK_NAME`, useful when reusing the same hook script for
+  multiple hook points.  It is set to the string name, also used by the
+  path, e.g., `hook/net/up`
+
+  For all hook points from hook/sys/shutdown and later, `FINIT_SHUTDOWN`
+  is also set, to one of: `halt`, `poweroff`, `reboot`
+
+* Fix #317: make sure hook scripts don't run twice, also fixes #316
+* Fix #318: only show `[ OK ] Calling foo` progress for `runparts ...`
+* Fix #320: the API/IPC socket is closed immediately at shutdown/reboot
+  to protect hook scripts or services calling initctl.  There is no way
+  to service these requests safely at that time
+* Fix #333: consider a service dirty if command line args have changed
+
+  This fixes `initctl reload` correctly restarting all daemons that have
+  new command line arguments.
+
+  Previously command line arguments changes were only acted upon if the
+  service was explicitly reloaded `initctl reload myservice`.
+
+  Found and fixed by Jack Newman
+
+* Fix #338: ensure shutdown hooks are called properly; `hook/sys/down`
+  and `hook/svc/down` hook scripts, found and fixed by Jack Newman
+* Fix #339: use absolute path in `/etc/finit.d/enabled/` symlinks, for
+  use-cases when `/etc` is read-only and `/etc/finit.d/enabled ->
+  /mnt/finit.d/enabled`, reported by Jack Newman
+* Fix #340: Finit ignores deleted/moved `.conf` file sin `/etc/finit.d`
+* Fix #342: in runlevel S (bootstrap), not all `initctl` commands can be
+  supported, block the following: runlevel, reload, start/stop, restart,
+  reload, halt, poweroff, suspend.  Also, prevent `SIGHUP` and `SIGUSR1`
+  signals when in shutdown or reboot
+* Fix #352: separate runlevel S from runlevel 0
+* Fix #355: regression in v3.2 stopping a process and its group
+
+  In Finit v3.2 a regression was introduced that affects the way Finit
+  stops a supervised process and its process group.
+
+  Instead of sending SIGTERM to the process, and thus delegating the
+  responsibility to that process to inform any children it may have, as
+  of commit 91a9c83 Finit sends SIGTERM to the entire process group.
+  For SIGKILL this is fine, SIGKILL only runs as cleanup and as a last
+  ditch effort if the process doesn't respond to SIGTERM.
+
+  This regression, introduced in v3.2, directly affects services like
+  `avahi-autoipd` that have forked off children that it needs to tell to
+  exit cleanly before it returns.  With the patch in question these
+  children are never allowed to complete, which in turn causes lingering
+  169.254 link-local addresses on interfaces.
+
+* Fix bootmisc plugin: octal permission on `/run/lock` and `/var/lock`
+
+* Ensure `initctl cond get` support the flux state (exit code 255)
+* Fix potential socket leak at bootstrap and shutdown
+* Fix potential NULL pointer deref in kernel command line parser
+* Fix lingering condition in service after reload of service with new
+  config that has no condition
+* Fix wrong path to command in service after reload, may have changed
+* `logit`: fall back to package name if `$LOGNAME` and `$USER` are
+  unset.  **Note:** you should probably not use `logit` in your own
+  scripts, it is only meant for internal use by Finit.  We recommend
+  using `logger` from the `bsdutils` or `sysklogd` packages instead
+* Fix issue where `env:`/`pre:`/`post:`/etc. is removed from a service
+
+  The trick is when reloading a service like this:
+
+        service env:/etc/env    serv -np -e foo:bar
+
+  into this:
+
+        service pre:/bin/pre.sh serv -np
+
+  In the second the `env:` has been removed and `pre:` added.  Prior to
+  this patch, `env:` was kept leading to unintended behavior.
+* Fix parse/diff of command line args, e.g., `nginx -g 'daemon off;'`
+
+  Starting a service like this works fine:
+
+        service [2345789] env:-/etc/default/nginx nginx -g 'daemon off;'
+
+  However, on `initctl reload` (and no change to .conf files) the arg
+  list was lost while parsing the .conf files.  Leading to a false
+  positive 'diff' in args causing nginx to be unnecessarily restarted.
+* Fix issue with disabled "linewrap" on the console TTY after login.
+  The root cause is `qemu-system-x86_64 -nographics` disabling it when
+  starting up.  The correct `\e[?7h` escape code is now used.
+
+
+[4.3][] - 2022-05-15
+--------------------
+
+Critical bug fix release.  If you run a 32-bit target with GLIBC 2.34
+you *need* to upgrade!
+
+> **Note:** system verbosity on console at start and shutdown has been
+>           increased.  Now the output of all commands is logged to the
+>           system logger, for early services `/dev/kmsg` is used.
+>
+> **Also:** please notice the updated support for enabling and disabling
+>           kernel and Finit debug messages on the system console.  Very
+>           useful when debugging either of them, e.g., a kernel module.
+>           For details, see [cmdline.md](doc/cmdline.md).
+
+### Changes
+* Support for overriding default runlevel from kernel command line.  Any
+  runlevel `[1-9]` may be selected, except 6 (reboot).  Issue #261
+* New command line option: `finit.fstab=/etc/fstab.custom`, with full
+  support for mounting, mount helpers, fsck, and swapon/off, issue #224
+* Support for special device `/dev/root`, which may not exist in `/dev`.
+  Finit now looks up the matching block device for `/` in `/sys/block/`
+* Loading `module`s no longer shows arguments in progress output
+* Warning messages in progress output now in yellow, not red, issue #214
+* `initctl`, new command line option `-V,--version` for ease of use
+* New condition `done` for run task, issue #207 by Ming Liu, Atlas Copco
+* Refactor parts of shutdown and reboot sequence for PREEMPT-RT kernels,
+  by Robert Andersson, Mathias Thore, and Ming Liu, Atlas Copco
+* Conditions for run/task/sysv status, e.g. `run/foo/success` and
+  `task/bar/failure`.  Issue #232, by Ming Liu, Atlas Copco
+* Conditions for services, can be used to synchronize other stanzas:
+  - `service/foo/running`
+  - `service/foo/halted`
+  - `service/foo/missing`
+  - `service/foo/crashed`
+  - `service/foo/stopped`
+  - `service/foo/busy`
+  - `service/foo/restart`
+* `initctl signal` support, by Jörgen Sigvardsson, issue #225
+* `initctl cond get` support to match `cond [set | clear]`, issue #255
+* `[WARN]` messages on console now printed in yellow, issue #214
+* Network services now also stopped when going to runlevel 6 (reboot),
+  not just runlevel 0 (shutdown) or 1 (single-user)
+* When `ifup` is missing on the system, bring at least `lo` up at boot
+* Log output from `ifup -a` (and `ifdown -a`), to syslog
+* Avoid blocking PID 1 when starting SysV init scripts
+* Allow custom `pid:` for SysV init scripts
+* Document supported types of forking/non-forking services
+* Auto-detect running in some common forms of containers
+* Simplify shutdown/reboot when running in a container
+* Log to `stderr` when running in a container w/o syslog daemon
+* Add support for `type:forking` to services, already supported but
+  with a very difficult `pid:` syntax, issue #223.  Docs updated
+* Support for setting global environment variables in `finit.conf`,
+  please note: this also affects Finit itself, be careful!
+* Extended environment variables for pre/post scripts, issue #189
+* Document secret service option `respawn`, which bypasses the crash
+  semantics, allowing endless restarts
+* Document secret `HOOK_BANNER`, the first hook point before the banner
+* Document slightly confusing `initctl reload foo` command.  It does
+  *not* reload the service's `.conf` file!  Issue #263
+* Log changes; all instances where previously the `basename cmd` of a
+  service was used to identify the service, now the proper `name:id` is
+  used instead.  Meaning, a service without a custom `:ID` or `name:`
+  will display the same as before, but with any of those customizations
+  the name and name:id will now be shown.  **Note:** this may affect any
+  log scrapers out there!
+* New plugin: `hook-scripts`, allows [run-parts(8)][] style scripts to
+  run on any hook point.  Contributed by Tobias Waldekranz
+* `initctl` (`reboot`) falls back to `-f` when it detects it is in
+  `sulogin` recovery mode, issue #247
+* The bundled `sulogin` is no longer enabled by default, in favor of
+  distribution versions.  Enable with `./configure --with-sulogin`
+* Support args to sysv-like scripts, e.g. `bridge-stp br0 start`
+* The `modules-load` plugin now skips all lines starting with `#` and
+  `;`.  Furthermore, files in `/etc/modules-load.d/*.conf` are now read
+  in lexicographic order and UNIX backup files (`foo.conf~`) are skipped
+* The `name:id` tuple is now more consistently used in all log and debug
+  messages instead of the basename of the command
+* Simplify error output of `initctl start/stop/restart/signal`, no more
+  extra usage help, just a plain error message
+* Exit codes of `initctl` have changed to use LSB script standard and BSD
+  sysexits.h exit codes.  As before, a non-zero exit is error or missing
+* Add support for `initctl -q` to more commands: stop, start, restart,
+  reload, signal, etc.
+
+[run-parts(8)]: https://manpages.debian.org/cgi-bin/man.cgi?query=run-parts
+
+### Fixes
+* Fix nasty 32/64-bit alignment issue between finit and its plugins,
+  applicable to 32-bit targets with GLIBC 2.34 and later.  External
+  plugins must make sure to use, at least: `-D_TIME_BITS=64`
+* Fix #215: disable cgroup support at runtime if kernel lacks support
+  or does not have the required controllers (cpu)
+* Fix #217: iwatcher initialization issue, by Ming Liu, Atlas Copco
+* Fix #218: initctl matches too many services, by Ming Liu, Atlas Copco
+* Fix #219: not all filesystems unmounted at shutdown, by Ming Liu, 
+  Mathias Thore, and Robert Andersson, Atlas Copco
+* Fix #226: initctl shows wrong PID for crashing services
+* Fix #227: reboot stalls if process stopped with `[WARN]`
+* Fix #233: initctl shows wrong status for run/task, by Sergio Morlans
+  and Ming Liu, Atlas Copco
+* Fix #248: source `env:file` also in `pre:` and `post` scripts
+* Fix #260: drop limit on device name in `Checking filesystem...` output
+* Fix start/stop and monitoring (restart) of SysV init scripts and
+  forking services, see the updated documentation for details
+* Fix call to `swapoff` at shutdown, does not support `-e` flag
+* Fix suspend to RAM issue.  Previously `reboot(RB_SW_SUSPEND)` was
+  used, now the modern `/sys/power/state` API is used instead.
+* Fix nasty run/task/service matcher bug, triggered by stanzas using the
+  same basename of a command but different `:ID`.  Caused Finit to match
+  with already registered but different run/task/service

+All services in runlevel S) are started first, followed by the desired
 run-time runlevel.  Run tasks in runlevel S can be started in sequence
 by using `run [S] cmd`.  Changing runlevels at runtime is done like any
 other init, e.g. <kbd>init 4</kbd>, but also using the more advanced
 `intictl` tool.
 
 
+**Conditions**
+
+As mentioned previously, Finit has an advanced dependency system to
+handle synchronization, called [conditions](doc/conditions.md).  It can
+be used in many ways; depend on another service, network availability,
+etc.
+
+One *really cool* example useful for embedded systems is to run certain
+scripts if a board has a certain feature encoded in its device tree.  At
+bootstrap we run the following `ident` script:
+
+```sh
+#!/bin/sh
+conddir=/var/run/finit/cond/hw/model
+dtmodel=/sys/firmware/devicetree/base/model
+
+if ! test -e $dtmodel; then
+    exit 0
+fi
+
+model=$(cat $dtmodel | tr "[A-Z] " "[a-z]-")
+mkdir -p $conddir && ln -s ../../reconf $conddir/$model
+```
+
+Provided the device tree node exists, and is a string, we can then use
+the condition `<hw/model/foo>` when starting other scripts.  Here is an
+example:
+
+```
+run  [S]                /path/to/ident    --
+task [2] <hw/model/foo> /path/to/foo-init -- Initializing Foo board
+```
+
+> [!TIP]

 ------------------------
@@ -320,8 +395,33 @@ Right after the runlevel change when all services have started properly,
 No configuration stanza in `/etc/finit.conf` is required for `rc.local`.
 If it exists and is an executable shell script Finit calls it at the very
 end of the boot, before calling the `HOOK_SYSTEM_UP`.  See more on hooks
-in [doc/plugins.md](doc/plugins.md#hooks), and about the system bootstrap
+in [doc/plugins.md](doc/plugins.md#hooks).
-in [doc/bootstrap.md](doc/bootstrap.md).
+
+
+### Limitations
+
+It is not possible to call Finit via signals or use `initctl` in any
+runparts or `/etc/rc.local` script.  This because Finit is single
+threaded and is calling these scripts in a blocking fashion at the end
+of runlevel S, at which point the event loop has not yet been started.
+
+The event loop is the whole thing which Finit is built around, except
+for runlevel S, which remains a slow procession through a lot of set up,
+with a few hooks and blocking call outs to external scripts.
+
+However, not all `initctl` commands are prohibited. Supported commands:
+
+ - `inictl cond`: only operate of files in `/run/finit/cond`
+ - `initctl enable/disable`: enabled run/task/service is activated on
+   the runlevel change from S to 2
+ - `initctl touch/show/create/delete/list`: `create`, provided the
+   non-interactive mode is used, again changes take effect in the
+   runlevel change directly after bootstrap
+ - `initctl -f reboot/poweroff/halt`: provided the `-f` flag is used to
+   force direct kernel commands
+
+**Example:** you can set a `usr/` condition in `/etc/rc.local` and have
+a service/task in runlevel 2 depend on it to execute.

+  points (see [Hooks](#hooks)).  _Optional plugin._
+
+  This plugin is particularly useful for early boot debugging that needs
+  to take place before regular services are available.
+
+  For example, say that you want to enable some kernel tracing before
+  modules are loaded. With hook scripts, you can just drop in a shell
+  script in `/libexec/finit/hook/mount/all/` that will poke the right
+  control files in tracefs.
+
+  Scripts are located in `/libexec/finit/hook` by default, this can be
+  customized at build-time using the `--with-hook-scripts-path=PATH`
+  argument to `configure`.
+
+* *hotplug.so*: Replaced with `/lib/finit/system/10-hotplug.conf`, which
+  checks for `udevd` and `mdev` at boot.  This file can be overridden by a
+  file in `/etc/finit.d/10-hotplug.conf`.
+
+  Enabled by default.
+  
+> [!TIP]
+> See the [Services](config.md#services) section in the configuration

 * *rtc.so*: Restore and save system clock from/to RTC on boot/halt.
+  Enabled by default.
 
-* *modules-load.so*: Scans /etc/modules-load.d for modules to modprobe.
+* *modules-load.so*: Scans `/etc/modules-load.d/*.conf` for modules to
+  load using `modprobe`.  Each file can contain multiple lines with the
+  name of the module to load.  Any line starting with the standard UNIX
+  comment character, `#`, or `;`, is skipped.
+  
+  Modules are by default loaded in runlevel `S` using the `task` stanza.
+  Each module gets a unique `name:modprobe.foo`, and optional`:ID`.  The
+  runlevel can be changed per file using:
+
+        set runlevel 2345
+
+  The `:ID` is a globally incremented index, which can be disabled per
+  file (anywhere) using the following config line:
+
+        set noindex
+
+  To change the index used by the plugin:
+
+        set index 1234
+
+  Since these tasks run in the background, they return `[ OK ]` at boot,
+  unless the modprobe tool does not exist.  Check syslog for warnings
+  and the actual status of the operation using `initctl`.
+
+> [!IMPORTANT]
+> Unlike the traditional .conf `module` directive, which load any listed

+
+### Forks to Background w/ PID File
+
+There are two syntax variants, type 1 and type 2.  The former is the
+traditional one used also for `sysv` start/stop scripts, and the latter
+is inspired by systemd, with a twist -- it lets Finit guess the pifdile
+to look for based on the standard path and the basename of the command.
+
+    service pid:!/run/serv.pid serv       -- Forking service, type 1
+    service type:forking       serv       -- Forking service, type 2
+
+In this example the resulting files to watch for are `/run/serv.pid` and
+`/var/run/serv.pid`, respectively.  On most modern Linux systems this is
+the same directory (`/var/run` is a symlink to `../run`).
+
+### Runs in Foreground w/ PID File
+
+    service                    serv -n -p -- Foreground service w/ PID file
+
+### Runs in Foreground w/o PID File
+
+Same as previous, but we tell Finit to create the PID file, because we
+need it to synchronize start/stop of a dependent service.
+
+    service pid:/run/serv.pid  serv -n    -- Foreground service w/o PID file
+
+### Runs in Foreground w/ Custom PID File

+ * This plugin scans files in /etc/modules-load.d/, for each line in the

+ * Each module is loaded when entering runlevel 2, 3, 4, or 5, using the
+ * modprobe tool.
+ *
+ * Loading is done by inserting a `task` stanza in Finit, ensuring all
+ * modules are loaded in parallel, with other modules and programs.
+ * Each `task` stanza is by default given the name:modprobe.module and
+ * indexed with `:ID`, starting with 1.
+ *
+ * Indexing can be disabled per file in /etc/modules-load.d/, anywwhere
+ * in a file, by putting the keyword `noindex` on a line of its own.  A
+ * noindex command can appear anywhere in the file, and up to the point
+ * it is read, tasks will be indexed with an incrementing `:ID`.  When
+ * `noindex` is read indexing is disabled and all subseequent tasks will
+ * not have any `:ID` at all.
+ *
+ * Please note, the :ID is there for your benefit, it ensures that tasks
+ * in Finit are unique.  If you have two tasks with the same name and ID
+ * (or no ID), the last one read replaces any preceding one!
